EPODILâ LV5Diluent

DESCRIPTION

Epodil LV5 diluent is a chemically inert, low viscosity liquid hydrocarbon resin. It is soluble in andcompatible with a wide variety of epoxy resins as well as most curing agents. Epodil LV5 diluent is aspecialized additive enhancing the performance properties of a formulated system and should be added atrelatively low loadings, in the order of 5 to 15 phr. Epodil LV5 diluent acts as a surface tension reducer, asa pigment wetting aid, and as an adhesion promoter. In the formulation of trowel able epoxy mortars, theaddition of Epodil LV5 diluent can help to improve trowel ability by reducing/eliminating the tendency fordrag or sticking to occur, so that it is not necessary to keep wetting the trowel with solvent to obtain asmooth surface. In epoxy mastic coatings for application to poorly prepared surfaces it aids penetration ofsurface rust and oil leading to improved adhesion.

The optimum level of Epodil LV5 diluent addition for any particular application will depend upon a variety offactors including types of resin, curing agents, fillers, substrates, etc.

PERFORMANCE EVALUATION

Epodil LV5 diluent was evaluated for its compatibility with liquid epoxy resin, impact on liquid epoxy resinviscosity, influence on reactivity, adhesion over sandblasted steel, influence on chemical resistance and 5%salt spray, following a 10 day ambient cure of applied coatings.

To perform the tests, liquid epoxy resin with EEW=190 was modified with Epodil LV5 diluent at the additionlevel of 5 and 15 phr. Unmodified liquid epoxy resin was used as a control.Many different curing agents were used to cure the modified and unmodified liquid epoxy resin and in alltests and the stoichiometry was 1 EEW to 1 AHEW.

COMPATIBILITY OF EPODIL® LV5 DILUENT WITH EPOXY RESIN AND CURING AGENTS: Epodil LV5diluent is compatible with most curing agents and with a variety of epoxy resins, making it a viable additivefor most epoxy systems. Compatibility with epoxy resin and curing agents were evaluated by mixing EpodilLV5 diluent with the liquid epoxy resin or with the curing agent up to the proportion of 1 part by weight ofEpodil LV5 diluent to 1 part by weight of liquid epoxy resin or curing agent. Blends were observedimmediately and after 24 hours. Table 1 shows the compatibility results.

IMPACT OF EPODIL LV5 DILUENT ON LIQUID EPOXY RESIN VISCOSITY: Epodil LV5 diluent reducesthe viscosity of liquid epoxy resin, allowing the formulators to increase the fillers and or pigmentsconcentration, or simply having a system with lower viscosity. Impact on liquid epoxy resin viscosity wasevaluated by modifying the liquid epoxy resin with Epodil LV5 at 5 and 15 phr. The viscosity for eachmixture was determined using a Brookfield viscosimeter after 24 hours. Figure 1 shows the impact ofEpodil LV5 diluent on resin viscosity.

INFLUENCE OF EPODIL LV5 DILUENT ON CURING AGENT REACTIVITY: Epodil LV5 diluent increasesthe pot life of ambient cured epoxy systems from 15 to 60%, depending on the curing agent and additionlevel of Epodil LV5 diluent. Influence on curing agent reactivity was determined by modifying the liquidepoxy resin with Epodil LV5 diluent at 5 and 15 phr.The reactivity was measured by viscosity increase during the pot life; the viscosity was determined using aBrookfield viscosimeter.The modified liquid epoxy resin and unmodified liquid epoxy resin were cured with Ancamineâ 1618 andAncamineâ 2432 curing agents. Figure 2 and 3 shows the impact of Epodil LV5 diluent on curing agentreactivity.

FIGURE 3: IMPACT ON CURING AGENT REACTIVITY USING ANCAMINEâ 2432 CURING AGENT

INFLUENCE OF EPODIL LV5 DILUENT ON ADHESION: Epodil LV5 diluent reduces the surface tension ofepoxy systems and as a consequence it helps to improve the adhesion of systems that do not have a goodsubstrate wetting characteristic. Adhesion improvement is dependent on the curing agent being used aswell as the addition level of Epodil LV5 diluent. For maximum performance tests varying the concentrationof Epodil LV5 diluent are recommended.

To determine the influence of Eposil LV5 diluent on adhesion the liquid epoxy resin was modified with 5and 15 phr of Epodil LV5 diluent. The curing agents selected for this evaluation were: Ancamine 1618,Ancamine 2280 and Ancamine 2432 curing agents. The clear coatings were brush-applied at a dry filmthickness of 100 to 125 m m (4-5 mils) over steel panels sandblasted to white metal (Sa3) and adhesion wasmeasured following a 10 days of cure at room temperature. Adhesion was measured according to ASTM3359 (tape adhesion and ASTM 4541 (pull-off test. The same was made to evaluate an unmodified liquidepoxy resin was used as a control. Table 2 shows the adhesion of modified and unmodified systems.

INFLUENCE OF EPODIL LV5 DILUENT ON CHEMICAL RESISTANCE: Epodil LV5 diluent improves theresistance of epoxy systems to diluted chemicals and water. A special improvement was observed on 10%solution of acetic acid. The impact of Epodil LV5 diluent on chemical resistance is dependent on the curingagent as well the addition level of Epodil LV5 diluent.

The influence of Epodil LV5 diluent on the chemical resistance was determined by modifying the liquidepoxy resin (LER with 5 and 15 phr. The modified epoxy resin was cured with Ancamide 350A, Ancamine1618, Ancamine 2280 and Ancamine 2432 curing agents. To perform the chemical resistance test, thesamples were cast and immersed in the various chemicals after a 10 day cure at room temperature. Thechemical resistance was checked by weight gain or loss after 7 and 28 days. The results obtained areexpressed on Table 3, 4, 5 and 6.

INFLUENCE OF EPODIL LV5 DILUENT ON CORROSION RESISTANCE: Epodil LV5 diluent when addedto a coating formulation maintains the high levels of corrosion resistance observed with 2 component epoxysystems. This is demonstrated by the excellent data obtained following exposure to salt spray resistanceweather testing.

To determine the influence of Epodil LV5 diluent on salt spray the liquid epoxy resin (LER was modifiedwith 5 and 15 phr of Epodil LV5 diluent. The curing agents selected for this evaluation were: Ancamide350A, Ancamine 1618, Ancamine 2280 and Ancamine 2432 curing agent. The clear coatings werebrush-applied at a dry film thickness of 100 to 125m m (4-5 mils) over steel panels sandblasted to whitemetal (Sa3. Salt spray test was performed according to ASTM B-117 after 10 days of cure at roomtemperature. Results obtained after 1,000 hours of exposure to salt spray cabinet are shown in pictures 1,
